To all 10/107715 it may concern Be it known that l, WALTER Jensen, acitizen of the United titates, residing at San Diego, in the county ofthin Diego and State of California, have invented eertaln new and usefulImprovements in ill/lining Devices, of which the'following 1s a spoolfication, reference heinghad to the accom-- panying drawings.

This invention relates to certain improve ments in mixing. devices andhas relation more particularly to a device of this gen eral characterespecially designed and adapt-- ed for use in the mixing of beverages.and it is an object of the invention to prov de a device of this generalcharacter having novel and improved means whereby the materials to bemixed are directed in a plurality of spiral streams of relativelydifferent lengths and wherein said streams will lntersect each other atspaced points during the return of said streams to the bottom of thecontainer in which the materials are being mixed.

Another object of the invention is to pro-- vide a novel and improveddevice of this general character which includes an exciter, togetherwith means for directing 1n the con tainer the material to be mined in aplurality of streams. n

Furthermore, it is anob ect oi the inven tion to provide a novelimproved device of this general character adapted to he ar ranged withina container and embodying a series of baflies or vanes arranged inflatedrelation one with respect to the remainder, said ba'liies or vanesoperating to divide the materials to be. mixed into separate streams orcurrents traveling in the same general direction.

it is still further an object of the invention to provide a novelimproved mining device adapted to be inserted in. the con tainer whereinthe materials are to be mixed and wherein said device embodies aplurality of balhes or vanes disposed in relatively ditferent obliquelyinclined planes with relation to the direction of flow of the ma terialsto be mixed, together with an enciter operating at a point below thevanes to cre ate the requisite agitation of the materials.

The invention consists in the details of con "auction and in thecombination and arrangement of the several parts oi my im proved ruiningdevice whereby certain H11"- portant advantages are attained and thedevice rendered simpler, less expensive and otherwise more convenientand adva11tageous for use, as will be hereinafter more fully set fortlnThe novel features of my invention will hereinafter be definitelyclaimed.

in order that my invention may be the better understood, ll will nowproceed to describe the same with reference to the accompanying drawingswherein,-

Figure 1 is a side elevation of a mixing" device embodying theimprovements of my invention.

Fig. 2 is a detail side elevation of the upper end of the device.

3 is a horizontal section on the line as of Fi 1.

Fig. 4; is a fragmentary sectional view of the baflies.

Fig. 5 is a top view thereof.

Fig. 6 is a bottom view thereof, and

Fig. 72' is an end view of one of the arms 17 hereinafter described.

its disclosed in the accompanying drawings, 1 denotes an upstandinghollow post having a hollow standard 2 in telescopic engagementtherewith and arranged within the base portion of the post i andcoacting with the standard 2 is a spring 3 for constantly urging thestandard 2 upwardly.

Extending forwardly from the upper portion of the standard 2 is abracket 4% which servesv as a support for the casing 5. Ar ranged withinthe casing 5 is an electric motor 6, including a depending shaft Ydisposed through the casing 5 and terminating adesired distancetherebelow. The motor 6 18 adapted to besuitably connected with adesired source of electrical energy and the standard 2 is provided withsuitable means for automatically controlling the circuit for said motor.its this controlling means forms no part of my present invention and isof a type now in use it is not believed necessary that a description orillustration thereof be given other than to state that when the standard2 is at the limit of its up ward movement the operating circuit isopened. and when the standard is forced downwardly said.circuit isclosed.

The lower portion of the post 1 is pro vided with a forwardly directedspring clip or jaw. 8 adapted to receive the lower portion of containerU in which beverage dti t lt

tea

' lower end of the shaft 7 terminates a sufficient distance above thetop of the container C to permit the ready removal or application ofsaid container with respect to the clip 8.

My improved mixing device as herein dis closed comprisesa pair ofvertically spaced cross arms 9 and 10 in perpendicularrelation with thecenters of said members 9 and 10 coplaner.

Depending from the opposite end portions of the upper cross member 9 arethe arms 11, each of a relatively short length and possessing a certaindegree of inherent resi'liency. The lower extremities of the arms 11 andthe extremities of the lower cross member 10 are connected by thebaffles or vanes B, said baffles or vanes being disposed in relativelydifierent inclined planes.

Each of the bafiiesor vanes B comprises a strip of material havingopposed side faces substantially fiat in cross section, said faces beinggradually increased in thickness from their lower end portions'to theirupper end portions and having their outer margins disposed on suchcurvature to cause said outer margins at all points throughout theirlength to have substantially close contact with the inner wall of thecontainer C when the mixing device is inserted therein.

The lower portion a and each of the baffles or vanes 13 is directedupwardly on a slight incline, such inclination of one of the bafiles orvanes B being reverse to that of the other. The upper portion 6 of eachof the vanes is disposed on a spiral.

Slidably disposed through central portions of the cross members 9 and10. is a shaft 12, said shaft being of a length in excess of thedistance between the cross members 9 and 10. Secured to the upper endportion of the shaft 12 is a clutch member 1 1 adapted to cooperate witha clutch member 15 carried by the lower end portion of the shaft 7, andwhen the standard 2 has been depressed. The clutch members 14 and 15 areparticularly illustrated and described in an application for patentexecuted on even date herewith.

Fixed to the lower end portion of the shaft 12 and below the lower crossmember 10 is an exciter E. The exciter E as herein disclosed comprises ahub 16 from which it radiates a plurality of arms 17. The arms 17 arepreferably equi-distantly placed in a direction circumferentially of thehub 16, and each of said arms is substantially V-shaped in cross sectionwith the apex rearwardly disposed with respect to the direction ofretatipnyof the shaft 12 as driven by the power seat 0 Each of the arms17 gradually increases in thickness from its inner end to its outer endand the forward base ofsaid arms has disposed longitudinally thereof agroove or channel 18 substantially V-shaped in cross section. The underportion of each of the arms 17 is stepped, as at 19.

A particular construction of the exciter when the shaft 12 is beingdriven from the power shaft 7 results in an effective excitement oragitation of the materials within the container C to be mixed while thebailles or vanes B operating to divide the agitated orexcited materialsinto separate spiral streams or currents which are of relativelydifferent lengths, so that the said streams or I currents will intersecteach other at spaced points during their return to the bottom of thecontainer.

The shaft 12 isconstantly urged upwardly through the instrumentality. ofan expanding element M interposed between the upper cross member 9 andthe clutch member 14-. By this means-the shaft 12 is capable of limitedwithholding movement which is of particular importance and advantage inorder to, facilitate the requisite cooperation between the clutchmembers 14 and 1F.

Carried by the standard 2 is a latch 20 adapted to engage a flange 21carried by the upper portion of the post 1, whereby the standard 2 maybe held depressed to maintain the clutch members 1 1 and 15 in workingengagement.

From the foregoing description it is thought to be obvious that a mixingdevice constructed in accordance with an embodiment of my invention isparticularly well adapted for use by reason of the convenience andfacility with which it maybe assembled and operated, and it will also beobvious that my invention is susceptible of some change and modificationwithout materially departing from the principles and spirit thereof,and'for this reason 1 do not wish to be understood as limiting myself tothe precise ar rangement and formation of the several parts herein shownin carrying out my in vention in practice except as hereinafter claimed.
